FIELD OF THE INVENTION

The present invention provides pyrazoline cannabinoid receptor antagonists/inverse agonists and pharmaceutical compositions thereof and methods of using the same for treating conditions including obesity, diabetes, hepatic disorders, cardiometabolic disorders, and/or cancers.

BACKGROUND OF THE INVENTION

Obesity is associated with an increase in the overall amount of adipose tissue (i.e., body fat), especially adipose tissue localized in the abdominal area. Obesity has reached epidemic proportions in the United States. The prevalence of obesity has steadily increased over the years among all racial and ethnic groups. The most recent data from the Centers for Disease Control and Prevention, and the National Center for Health Statistics report 66% of the adult population overweight (BMI, 25.0-29.9), 31% obese (BMI, 30-39.9), and 5% extremely obese (BMI, ≧40.0). Among children aged 6 through 19 years, 32% were overweight and 17% were obese. This translates to 124 million Americans medically overweight, and 44 million of these deemed obese. Obesity is responsible for more than 300,000 deaths annually, and will soon overtake tobacco usage as the primary cause of preventable death in the United States. Obesity is a chronic disease that contributes directly to numerous dangerous co-morbidities, including type 2 diabetes, cardiometabolic diseases, hepatic disorders, cardiovascular disease, inflammatory diseases, premature aging, and some forms of cancer. Type 2 diabetes, a serious and life-threatening disorder with growing prevalence in both adult and childhood populations, is currently the 7^(th) leading cause of death in the United States. Since more than 80% of patients with type 2 diabetes are overweight, obesity is the greatest risk factor for developing type 2 diabetes. Increasing clinical evidence indicates that the best way to control type 2 diabetes is to reduce weight.

The most popular over-the counter drugs for the treatment of obesity, phenylpropanolamine and ephedrine, and the most popular prescription drug, fenfluramine, were removed from the marketplace as a result of safety concerns. Drugs currently approved for the long-term treatment of obesity fall into two categories: (a) CNS appetite suppressants such as sibutramine and rimonabant, and (b) gut lipase inhibitors such as orlistat. CNS appetite suppressants reduce eating behavior through activation of the ‘satiety center’ in the brain and/or by inhibition of the ‘hunger center’ in the brain. Gut lipase inhibitors reduce the absorption of dietary fat from the gastrointestinal (GI) tract. Although appetite suppressants and gut lipase inhibitors work through very different mechanisms, they share in common the same overall goal of reducing body weight secondary to reducing the amount of calories that reach the systemic circulation. Unfortunately, these indirect therapies produce only a modest initial weight loss (approximately 5% compared to placebo) that is usually not maintained. After one or two years of treatment, most patients return to or exceed their starting weight. In addition, most approved anti-obesity therapeutics produce undesirable and often dangerous side effects that can complicate treatment and interfere with a patient's quality of life.

The lack of therapeutic effectiveness, coupled with the spiraling obesity epidemic, positions the ‘treatment of obesity’ as one of the largest and most urgent unmet medical needs. There is, therefore, a real and continuing need for the development of improved medications that treat or prevent obesity.

The endocanabinoid system, comprised of the canabinoid receptors (CB1 and CB2) and their endogenous ligands (e.g., anandamide, 2-AG), plays a prominent role in the control of food intake and energy metabolism. CB1 receptors are widely expressed in the brain, including cortex, hippocampus, amygdala, pituitary and hypothalamus. CB1 receptors have also been identified in numerous peripheral organs and tissues, including thyroid gland, adrenal gland, reproductive organs, adipose tissue, liver, muscle, pancreas, and gastrointestinal tract. CB2 receptors are localized almost exclusively in immune and blood cells [Endocrine Reviews 2006, 27, 73].

The plant-derived cannabinoid agonist Δ⁹-tetrahydrocannabinol (Δ⁹-THC), the main psychoactive component of marijuana, binds to both CB1 and CB2 receptors. Δ⁹-THC is widely reported to increase appetite and food intake (hyperphagia) in humans and in animals. This hyperphagic effect is largely blocked by pretreatment with selective CB 1 receptor blockers (i.e., CB1 blockers)(e.g., rimonabant (SR141716A, Acomplia®)), strongly supporting the belief that CB1 receptor activation mediates the hyperphagic effect of Δ⁹-THC, [Endocrine Reviews 2006, 27, 73].

In humans, rimonabant produces a clinically meaningful weight loss in obese patients. Obese patients also experience improvements in diabetic and cardiometabolic risk factors associated with obesity, including an increase in the level of high density lipoprotein cholesterol (HDL), and decreases in triglycerides, glucose, and hemoglobin A1c (HbA1c, a marker of cumulative exposure to glucose) levels. Rimonabant also produces greater reductions in abdominal fat deposits, which are a known risk factor for diabetes and heart disease [Science 2006, 311, 323]. Taken together, these improvements in adiposity and cardiometabolic risk factors produce an overall decrease in the prevalence of the metabolic syndrome [Lancet 2005, 365, 1389 and NEJM 2005, 353, 2121].

In patients with type 2 diabetes not currently treated with other anti-diabetic medications, rimonabant was shown to significantly improve blood sugar control and weight, as well as other risk factors such as HDL and triglycerides, when compared to placebo (Lancet 2006, 368(9548), 1660-72). After six months of treatment, HbA1c levels were significantly lowered by 0.8% from a baseline value of 7.9 as compared to a reduction of 0.3% in the placebo group. These results are consistent with preclinical studies that demonstrate improved glycemic and lipid control in diabetic and dyslipedemic mice, rats, and dogs (Pharmacology Biochemistry & Behavior, 2006, 84, 353; American Journal of Physiology, 2003, 284, R345; American Diabetes Association Annual Meeting, 2007; Abstract Number 0372-OR).

The beneficial effects of rimonabant on diabetic and cardiometabolic risk factors such as high blood pressure, insulin resistance, and eleveated triglycerides cannot be explained by diet-related weight loss alone. For example, in patients receiving 20 mg of rimonabant, only approximately 50% of the beneficial effects on triglycerides, fasting insulin, and insulin resistance can be accounted for by weight loss secondary to reduced food intake. These results suggest a direct pharmacological effect of CB1 antagonists on glucose and lipid metabolism, in addition to indirect effects on metabolism secondary to hypophagia-mediated weight loss [Science 2006, 311, 323 and JAMA 2006, 311, 323]. Taken together, these results suggest that CB1 antagonists might be effective in the treatment of diabetes, dyslipidemia, cardiovascular disorders (e.g., atherosclerosis, hypertension), and hepatic disorders (e.g., cirrhosis, fatty liver diseases), even in patients that are not clinically overweight or obese.

The CB1 receptor is one of the most abundant and widely distributed G protein-coupled receptors in the mammalian brain. It is believed that the appetite-suppressant properties of CB1 antagonists are mediated through an interaction with CB1 receptors in the hypothalamus (regulation of food intake), and in the mesolimbic region (rewarding properties of food). However, CB1 receptors are far more broadly distributed in brain (e.g., neocortex, hippocampus, thalamus, cerebellum, and pituitary), and while interacting with targeted CB1 receptors in hypothalamus and mesolimbic regions to suppress appetite, CB1 antagonists have equal access to non-targeted CB1 receptors that have little if any role in appetite control. Binding to non-targeted receptors can often lead to unwanted side effects of CNS drugs [Endocrine Reviews 2006, 27: 73]. The CB1 blockers rimonabant and taranabant produce psychiatric and neurological side effects. These include depressed mood, anxiety, irritability, insomnia, dizziness, headache, seizures, and suicidality.

These side effects are dose-related and appear pronounced at the most efficacious weight-reducing doses of rimonabant and taranabant (JAMA 2006, 311, 323; Cell Metabolism 2008, 7, 68). The occurrence of therapeutic efficacy (appetite suppression) and side effects over the same dose range strongly suggest that both effects are mediated through concurrent antagonism of CB1 receptors in both ‘targeted’ and ‘non-targeted’ brain regions. Brain-penetrant CB1 blockers do not selectively target CB1 receptors in efficacy brain regions, while ignoring CB1 receptors in side effect brain regions.

The beneficial effects of the CB1 antagonist rimonabant on body weight, adiposity, and diabetic and cardiometabolic risk factors such as high blood pressure, insulin resistance and blood lipids cannot be explained by weight loss derived from CNS-mediated appetite suppression alone [JAMA 2006, 311, 323]. Approximately 50% of the benefit is likely derived from an interaction with CB1 receptors in peripheral tissues known to play an active role in metabolism. These include adipose tissue, liver, muscle, pancreas, and gastrointestinal tract.

SLV319 (Compound AA) is a drug that is indicated for the treatment of obesity. Compounds like SLV319 and related compounds have been described in various publications including J. Med. Chem. 2004, 47(3), 627 and U.S. Pat. No. 6,476,060.

Des-phenyl analogs of AA (e.g., Structure BB) are described in Biorg. Med. Chem. Lett. 2005, 15, 4793 and U.S. Pat. No. 6,974,810. Des-phenyl analogs of this sort are not considered to be part of the present invention.

In view of the above, it is highly desirable to find effective and highly selective CB1 receptor blockers with limited or no CNS adverse side effects, including mood disorders. Particularly, it is desirable to find compounds that preferentially target CB1 receptors in peripheral tissues (e.g., adipose tissue, liver, muscle, pancreas, and gastrointestinal tract), while sparing CB1 receptors in brain. In this way, peripherally-mediated beneficial effects of CB1 blockers should be maintained, whereas CNS side effects should be reduced or eliminated. This should provide a novel opportunity to develop safer alternatives to highly brain penetrant CB1 blockers for the prevention or treatment of obesity, diabetes, dyslipidemia, cardiovascular disorders, hepatic disorders, and/or cancers.

In another aspect, the present invention provides the use of novel compounds for the manufacture of a medicament for the treatment of obesity, diabetes, dyslipidemias, cardiovascular disorders, inflammatory disorders, hepatic disorders, and/or cancers.

These and other objects, which will become apparent during the following detailed description, have been achieved by the inventors' discovery that the presently claimed compounds or pharmaceutically acceptable salt forms thereof are expected to be effective CB1 receptor blockers.

DETAILED DESCRIPTION OF THE INVENTION

All references cited herein are hereby incorporated in their entirety herein by reference.

A CB1 blocker is a neutral CB1 receptor antagonist and/or a CB1 receptor inverse agonist.

The present invention is based on the finding that a CB1 receptor blocker has beneficial effects on cardiometabolic disorders including obesity, diabetes, and dyslipidemia that cannot be explained by weight loss derived from CNS-mediated appetite suppression alone, and that this effect is mediated, at least in part, through interaction at peripheral CB1 receptors. To this end, the present invention provides compounds that are designed to preferentially target CB1 receptors in peripheral tissues (e.g., adipose tissue, liver, muscle, pancreas, and gastrointestinal tract), while sparing CB1 receptors in brain. With these types of compounds, peripherally-mediated beneficial effects of CB1 blockers should be maintained, whereas CNS side effects should be reduced or eliminated.

The compounds of the present invention have been designed to have reduced CNS exposure by virtue of their inability or limited ability to penetrate the blood-brain barrier (BBB), or by their participation in active transport systems, thus reducing centrally mediated side-effects, a potential problem with many anti-obesity agents. It is expected that the peripherally restricted compounds of the present invention will have no or very limited CNS effects, including mood disorders, seizures, and suicidality. Thus, their peripherally mediated CB1 antaonistic properties should provide therapeutic agents with greater safety.

Moreover, if the maximum dosage of a drug used in the treatment of obesity, diabetes, dyslipidemia, cardiovascular disorders, inflammatory disorders, hepatic disorders, and/or cancers is limited as a result of CNS side effects (e.g., seizures, depression, anxiety, suicidality, movement disorders, and hyperactivity), incorporation of a peripherally restricting group in such a drug would lower the brain concentration of the drug relative to the concentration in the systemic circulation, thereby affording the opportunity to increase the dosage employed to treat the peripheral disorder (e.g., obesity, diabetes, dyslipidemia, cardiovascular disorders, inflammatory disorders, hepatic disorders, and/or cancers). The increased dosage may provide greater therapeutic efficacy, as well as a more rapid onset of therapeutic action.

“Mammal” and “patient” cover warm blooded mammals that are typically under medical care (e.g., humans and domesticated animals). Examples include feline, canine, equine, bovine, and human, as well as just human.

“Treating” or “treatment” covers the treatment of a disease-state in a mammal, and includes: (a) preventing the disease-state from occurring in a mammal, in particular, when such mammal is predisposed to the disease-state but has not yet been diagnosed as having it; (b) inhibiting the disease-state, e.g., arresting it development; and/or (c) relieving the disease-state, e.g., causing regression of the disease state until a desired endpoint is reached. Treating also includes the amelioration of a symptom of a disease (e.g., lessen the pain or discomfort), wherein such amelioration may or may not be directly affecting the disease (e.g., cause, transmission, expression, etc.).

“Pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include, but are not limited to, those derived from inorganic and organic acids selected from 1,2-ethanedisulfonic, 2-acetoxybenzoic, 2-hydroxyethanesulfonic, acetic, ascorbic, benzenesulfonic, benzoic, bicarbonic, carbonic, citric, edetic, ethane disulfonic, ethane sulfonic, fumaric, glucoheptonic, gluconic, glutamic, glycolic, glycollyarsanilic, hexylresorcinic, hydrabamic, hydrobromic, hydrochloric, hydroiodide, hydroxymaleic, hydroxynaphthoic, isethionic, lactic, lactobionic, lauryl sulfonic, maleic, malic, mandelic, methanesulfonic, napsylic, nitric, oxalic, pamoic, pantothenic, phenylacetic, phosphoric, polygalacturonic, propionic, salicyclic, stearic, subacetic, succinic, sulfamic, sulfanilic, sulfuric, tannic, tartaric, and toluenesulfonic.

The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound that contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, non-aqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are useful. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 18th ed., Mack Publishing Company, Easton, Pa., 1990, p 1445, the disclosure of which is hereby incorporated by reference.

“Therapeutically effective amount” includes an amount of a compound of the present invention that is effective when administered alone or in combination to treat obesity, diabetes, dyslipidemias, cardiovascular disorders, inflammatory disorders, hepatic disorders, cancers, and a combination or comorbitity thereof, or another indication listed herein. “Therapeutically effective amount” also includes an amount of the combination of compounds claimed that is effective to treat the desired indication. The combination of compounds can be a synergistic combination. Synergy, as described, for example, by Chou and Talalay, Adv. Enzyme Regul. 1984, 22:27-55, occurs when the effect of the compounds when administered in combination is greater than the additive effect of the compounds when administered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at sub-optimal concentrations of the compounds. Synergy can be in terms of lower cytotoxicity, increased effect, or some other beneficial effect of the combination compared with the individual components.

Obesity is defined as having a body mass index (BMI) of 30 or above. The index is a measure of an individual's body weight relative to height. BMI is calculated by dividing body weight (in kilograms) by height (in meters) squared. Normal and healthy body weight is defined as having a BMI between 20 and 24.9. Overweight is defined as having a BMI≧25. Obesity has reached epidemic proportions in the U.S., with 44 million obese Americans, and an additional eighty million deemed medically overweight.

Obesity is a disease characterized as a condition resulting from the excess accumulation of adipose tissue, especially adipose tissue localized in the abdominal area. It is desirable to treat overweight or obese patients by reducing their amount of adipose tissue, and thereby reducing their overall body weight to within the normal range for their sex and height. In this way, their risk for co-morbidities such as diabetes, dyllipidemias, cardiovascular disorders, inflammatory disorders, hepatic disorders, and cancers will be reduced. It is also desirable to prevent normal weight individuals from accumulating additional, excess adipose tissue, effectively maintaining their body weights at a BMI<25, and preventing the development of co-morbidities. It is also desirable to control obesity, effectively preventing overweight and obese individuals from accumulating additional, excess adipose tissue, reducing the risk of further exacerbating their co-morbidities.

Type 2 Diabetes or Diabetes mellitus type 2 or (formerly called non-insulin-dependent diabetes mellitus (NIDDM), or adult-onset diabetes) is a metabolic disorder that is primarily characterized by insulin resistance, relative insulin deficiency, and hyperglycemia. The World Health Organization definition of diabetes is for a single raised glucose reading with symptoms otherwise raised values on two occasions, of either fasting plasma glucose≧7.0 mmol/l (126 mg/dl) or with a Glucose tolerance test: two hours after the oral dose a plasma glucose≧11.1 mmol/l (200 mg/dl). Type 2 Diabetes is rapidly increasing in the developed world and there is some evidence that this pattern will be followed in much of the rest of the world in coming years. CDC has characterized the increase as an epidemic (Diabetes, Atlanta: Centres for Disease Control, Atlanta, Report no. 2007-05-24). In addition, whereas this disease used to be seen primarily in adults over age 40 (in contrast to Diabetes mellitus type 1), it is now increasingly seen in children and adolescents, an increase thought to be linked to rising rates of obesity in this age group.

Insulin resistance means that body cells do not respond appropriately when insulin is present. Unlike insulin-dependent diabetes mellitus (Type 1), the insulin resistance is generally “post-receptor”, meaning it is a problem with the cells that respond to insulin rather than a problem with insulin production. Type 2 diabetes is presently of unknown etiology (i.e., origin). About 90-95% of all North American cases of diabetes are type 2, and about 20% of the population over the age of 65 has diabetes mellitus Type 2 (Nature, 2001, 414, 6865). Diabetes affects over 150 million people worldwide and this number is expected to double by 2025. About 55 percent of type 2 diabetics are obese-chronic obesity leads to increased insulin resistance that can develop into diabetes (Morbidity and Mortality Weekly Report 2008, 53, 1066). Type 2 diabetes is often associated with obesity, hypertension, elevated cholesterol (combined hyperlipidemia), and with the condition often termed Metabolic syndrome (it is also known as Syndrome X, Reavan's syndrome, or CHAOS). There are several drugs available for Type 2 diabetics, including metformin, thiazolidinediones, which increase tissue insulin sensitivity, α-glucosidase inhibitors which interfere with absorption of some glucose containing nutrients, and peptide analogs that must be injected.

Dyslipidemia is the presence of abnormal levels of lipids and/or lipoproteins in the blood. Lipids (fatty molecules) are transported in a protein capsule, and the density of the lipids and type of protein determines the fate of the particle and its influence on metabolism. Lipid and lipoprotein abnormalities are extremely common in the general population, and are regarded as a highly modifiable risk factor for cardiovascular disease due to the influence of cholesterol, one of the most clinically relevant lipid substances, on atherosclerosis. In addition, some forms may predispose to acute pancreatitis.

In western societies, most dyslipidemias are hyperlipidemias; that is, an elevation of lipids in the blood, often due to diet and lifestyle. The prolonged elevation of insulin levels can also lead to dyslipidemia. The most prevalent hyperlipidemias include: hypercholesterolemia, characterized by elevated cholesterol (usually LDL), hypertriglyceridemia, characterized by elevated triglycerides (TGs); hyperlipoproteinemia, characterized by elevated lipoproteins; hyperchylomicronemia, characterized by elevated chylomicrons; and combined hyperlipidemia, characterized by elevated LDL and triglycerides. Abnormal decreases in the levels of lipids and/or lipoproteins in the blood also can occur. These include hypocholesterolemia, characterized by lowered cholesterol (usually high density lipoprotein, or HDL); and abetalipoproteinemia, characterized by lowered beta lipoproteins.

Dyslipidemia contributes to the development of atherosclerosis. Causes may be primary (genetic) or secondary. Diagnosis is by measuring plasma levels of total cholesterol, TGs, and individual lipoproteins. Treatment is dietary changes, exercise, and lipid-lowering drugs. A linear relation probably exists between lipid levels and cardiovascular risk, so many people with “normal” cholesterol levels benefit from achieving still lower levels. Normal and abnormal lipid levels have been defined in the Third Report of the Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults. National Institutes of Health, National Heart, Lung, and Blood Institute, 2001.

The treatment of choice for dyslipidemias is lifestyle change, including diet and exercise. Drugs are the next step when lifestyle changes are not effective. Lipid lowering drugs include statins, nicotinic acid, bile acid sequestrants, fibrates, cholesterol absorption inhibitors, and combination treatments (e.g., niacin and a statin). These agents are not without adverse effects, including flushing and impaired glucose tolerance (nicotinic acid), bloating, nausea, cramping, and constipation (bile acid sequestrants). Bile acid sequestrants may also increase TGs, so their use is contraindicated in patients with hypertriglyceridemia. Fibrates potentiate muscle toxicity when used with statins, and may increase LDL in patients with high TGs.

There are many kinds of hepatic (i.e., liver) diseases. Viruses cause some of them, like hepatitis A, hepatitis B and hepatitis C. Others can be the result of drugs, poisons or drinking too much alcohol. If the liver forms scar tissue because of an illness, it's called cirrhosis. Jaundice, or yellowing of the skin, can be one sign of hepatic disease. Cancer can affect the liver. Hepatic diseases such as hemochromatosis can be inherited. Additional liver diseases include nonalcohol steatohepatitis (NASH), alcoholic liver disease, cholangiocarcinoma, hepatic encephalopathy, hepatic failure, liver abscess, liver tumors, liver coagulopathy, glycogen storage diseases, portal hypertension, primary biliary cirrhosis, and primary sclerosing cholangitis.

There are few good treatment options for liver diseases. Options include lifestyle change (including diet and exercise), liver transplantation, and insertion of a transjugular intrahepatic portosystemic shunt that is placed in veins in the middle of the liver to improve blood flow to and from the organ. There are few effective drug treatment options for hepatic diseases. Interferon is an FDA-approved drug for the treatment of viral hepatitis. The chimeric protein Hyper-IL-6 dramatically enhances hepatocyte proliferation and is currently being evaluated as a pharmacological treatment for liver injury.

Drugs enter the CNS from the systemic circulation by crossing the blood-brain barrier (BBB). The BBB is a highly specialized ‘gate-keeper’ that protects the brain by preventing the entry of many potentially harmful substances into the CNS from the systemic circulation. Much is known about the BBB, and of the physical-chemical properties required for compounds transported across it.

Drugs that do not cross the BBB into the CNS or that are readily eliminated through transport mechanisms (J. Clin. Invest. 1996, 97, 2517) are known in the literature and have low CNS activity due to their inability to develop brain levels necessary for pharmacological action. The BBB has at least one mechanism to remove drugs prior to their accumulation in the CNS. P-Glycoproteins (P-gp) localized in plasma membrane of the BBB can influence the brain penetration and pharmacological activity of many drugs through translocation across membranes. The lack of accumulation into the brain by some drugs can be explained by their active removal from the brain by P-gp residing in the BBB. For example, the typical opioid drug loperamide, clinically used as an antidiarrheal, is actively removed from the brain by P-gp, thus explaining its lack of opiate-like CNS effects. Another example is domperidone, a dopamine receptor blocker that participates in the P-gp transport (J. Clin. Invest. 1996, 97, 2517). Whereas dopamine receptor blockers that cross the BBB can be used to treat schizophrenia, the readily-eliminated domperidone can be used to prevent emesis, without the likelihood of producing adverse CNS effects.

In addition to the above compounds, agents possessing structural characteristics that retard or prevent BBB penetration or contribute to participation in active elimination processes have been identified in various classes of therapeutics. These include antihistamines (Drug Metab. Dispos. 2003, 31, 312), beta-adrenergic receptor antagonists (Eur. J. Clin. Pharmacol. 1985, 28, Suppl: 21; Br. J. Clin. Pharmacol., 1981, 11, 549), non-nucleoside reverse transcriptase inhibitors (NNRTIs, J. Pharm. Sci., 1999, 88, 950), and opioid antagonists. This latter group has been tested in relation to their activity in the gastrointestinal tract. These peripherally selective opioid antagonists are described in various US patents as being useful in the treatment of non-CNS pathologies in mammals, in particular those of the gastrointestinal tract [see U.S. Pat. No. 5,260,542; U.S. Pat. No. 5,434,171; U.S. Pat. No. 5,159,081; and U.S. Pat. No. 5,270,238].

Other types of non-brain penetrant compounds can be prepared through the creation of a charge within the molecule. Thus, the addition of a methyl group to the tertiary amine functionality of the drugs scopolamine or atropine, unlike the parent molecules, prevents their passage across the BBB through the presence of a positive charge. However, the new molecules (methyl-scopolamine and methyl-atropine) retain their full anticholinergic pharmacological properties. As such, these drugs can also be used to treat peripheral diseases, without the concern of adverse CNS effects. The quaternary ammonium compound methylnaltrexone is also used for the prevention and/or treatment of opioid-induced gastrointestinal side effects associated with opioid administration (J. Pharmacol. Exp. Ther. 2002, 300, 118).

The discovery that the anti-obesity activity of cannabinoid receptor blockers may in part be mediated by a non-CNS mechanism could make it beneficial for the compounds of the present invention to be peripherally restricted (i.e., have an inability or limited ability to cross the BBB, or be readily eliminated from the brain through active transport systems). It may be desirable for the compounds of the present invention to be peripherally restricted, which in turn will result in no or very limited CNS effects. Compounds that provide peripherally mediated efficacy in treating obesity, diabetes, dyslipidemias, cardiovascular disorders, inflammatory disorders, hepatic disorders, cancers, a comorbitity thereof, or a combination or should result in therapeutic agents with greater safety. It can be desirable that the compounds of the present invention, when administered in a therapeutically effective amount, have no or very limited CNS effects. It can also be desirable that the lack of CNS effects is a result of the compounds of the present invention having minimal brain concentrations when administered in therapeutically effective amounts. In this context, minimal brain concentrations means levels that are too low to be therapeutically effective for the treatment of a CNS indication or too low to cause significant or measurable deleterious or undesired side effects, or both.

SLV319 (Compound AA) is a drug that crosses the BBB and is indicated for the treatment of obesity. It is believed that SLV319 works to treat obesity in part via a CNS mechanism. Compounds like SLV319 and related compounds have been described in various publications including J. Med. Chem. 2004, 47(3), 627 and U.S. Pat. No. 6,476,060.

Des-phenyl analogs of AA are described in Biorg. Med. Chem. Lett. 2005, 15, 4793 and U.S. Pat. No. 6,974,810. In compound I, which is also a des-phenyl analog of AA, one of R^(d), R^(e), X, Y, X′, Y′, Z, Z′, or Q is a group capable of reducing or limiting the CNS activity of compound I. This reduced or limited CNS activity occurs via at least one of R^(d), R^(e), X, Y, X′, Y′, Z, Z′, and Q being a group that either limits compound I's ability to cross the BBB relative to that of SLV319 or enables it to be actively removed from the brain at a rate greater than that of SLV319. Examples of the amount of compound I present in the brain can include (a) from 50, 55, 60, 65, 70, 75, 80, 85, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, to 100% lower than SLV319, (b) from 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, to 100% lower than SLV319, and (c) from 98, 99, to 100% lower than SLV319, when administered at the same dosage.

The compounds of the present invention have been shown to be active cannabinoid receptor blockers (e.g., have activity at ≦10 μM). The compounds of the present invention are typically CB1 cannabinoid receptor blockers. However, CB1 blockers frequently are also CB2 blockers (i.e., CB2 antagonists or inverse agonists). Thus the present invention also includes CB2 blockers and compounds that are both CB1 and CB2 blockers.

An inverse agonist is a compound that not only blocks the action of the endogenous agonist at the receptor, but also exhibits its own activity which is usually the opposite of that shown by the agonist. Inverse agonists are also effective against certain types of receptors (e.g. certain histamine receptors/GABA receptors) that have intrinsic activity without the interaction of a ligand upon them (also referred to as ‘constitutive activity’).

Most methods of treating obesity are dependent on a significant reduction in energy intake, either by a decrease in food intake (e.g., sibutramine) or by inhibition of fat absorption (e.g., orlistat). In the present invention, adipose tissue may be reduced in the absence of a significant reduction in food intake. The weight loss, as a result of the present invention, comes from the treatment with a compound of the present invention, largely independent of, though not totally dissociated from, appetite and food intake. It can be desirable that adipose tissue loss occurs while food intake is maintained, increased or (a) about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20% below the normal range of the subject prior to being treated in accordance with the present invention (i.e., its pre-administration level), (b) about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15% below its pre-administration level, (c) about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% below its pre-administration level, or (d) about 1, 2, 3, 4, or 5% below its pre-administration level.

In some cases, loss of adipose tissue can be accompanied by a concomitant loss of lean muscle mass. This is particularly evident in cancer patients who show a generalized wasting of body tissues, including adipose tissue and lean muscle mass. In the present invention, however, it can be desirable for body fat to be significantly reduced in the absence of a significant reduction in lean body mass. Adipose tissue loss comes from treatment with a compound of the present invention, independent of a significant change in lean body mass. Thus, adipose tissue loss can occur while lean body mass is maintained, increased, or (a) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30% below the normal range of the subject prior to being treated in accordance with the present invention (i.e., its pre-administration level), (b) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15% below pre-administration levels, (c) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% below pre-administration levels, or (d) is no more than about 1, 2, 3, 4, or 5% below pre-administration levels.

In some cases, loss of adipose tissue can be accompanied by a concomitant loss of water mass. This is particularly evident with diet regimens that promote dehydration. In the present invention, it can be desirable for body fat to be significantly reduced in the absence of a significant reduction in water mass. In other words, adipose tissue loss comes from treatment with a compound of the present invention, independent of a significant change in water mass. It can be desirable that adipose tissue loss occurs while water mass is maintained, increased, or (a) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30% below the normal range of the subject prior to being treated in accordance with the present invention (i.e., its pre-administration level), (b) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15% below pre-administration levels, (c) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% below pre-administration levels, or (d) is no more than about 1, 2, 3, 4, or 5% below pre-administration levels.

Sibutramine and orlistat are currently marketed for use in the treatment of obesity, albeit weight loss is achieved through entirely different mechanism of action. Sibutramine inhibits the neuronal reuptake of serotonin and noradrenaline, and orlistat inhibits gut lipase enzymes that are responsible for breaking down ingested fat.

Cannabinoid receptor blockers can promote weight loss through inhibition of peripheral cannabinoid receptors, a mechanism entirely different from appetite suppressants, gut lipase inhibitors, and other agents with similar indications (e.g., serotonin agonists, leptin, fatty acid synthase inhibitors, and monoamine oxidase (MAO) inhibitors). Co-administration of a cannabinoid receptor blocker together with one or more other agents that are useful for treating the indications described above (e.g., obesity, diabetes, dyslipidemias, cardiovascular disorders, inflammatory disorders, hepatic disorders, cancers, and a combination thereof) is expected to be beneficial, by producing, for example, either additive or synergistic effects. Examples of additional agents include an appetite suppressant, a lipase inhibitor, and a MAO inhibitor (e.g., MAO-B and a combination of MAO-A/B). Therefore, the present invention provides a method of treating obesity, diabetes, dyslipidemias, cardiovascular disorders, inflammatory disorders, hepatic disorders, and/or cancers, and a combination thereof, comprising administering a therapeutically effective amount of a compound of the present invention and a second component effective for treating the desired indication.

Examples of second components include anti-obesity agents, which include, but are not limited to: 1) growth hormone secretagogues; 2) growth hormone secretagogue receptor agonists/antagonists; 3) melanocortin agonists; 4) Mc4r (melanocortin 4 receptor) agonists; 5) .beta.-3 agonists; 7) 5HT2C (serotonin receptor 2C) agonists; 8) orexin antagonists; 9) melanin concentrating hormone antagonists; 10) melanin-concentrating hormone 1 receptor (MCH1R) antagonists; 11) melanin-concentrating hormone 2 receptor (MCH2R) agonist/antagonists; 12) galanin antagonists; 13) CCK agonists; 14) CCK-A (cholecystokinin-A) agonists; 16) corticotropin-releasing hormone agonists; 17) NPY 5 antagonists; 18) NPY 1 antagonists; 19) histamine receptor-3 (H3) modulators; 20) histamine receptor-3 (H3) blockers; 21) β-hydroxy steroid dehydrogenase-1 inhibitors (.beta.-HSD-1); 22) PDE (phosphodiesterase) inhibitors; 23) phosphodiesterase-3B (PDE3B) inhibitors; 24) NE (norepinephrine) transport inhibitors; 25) non-selective serotonin/norepinephrine transport inhibitors, such as sibutramine, phentermine, or fenfluramine; 26) ghrelin antagonists; 28) leptin derivatives; 29) BRS3 (bombesin receptor subtype 3) agonists; 30) CNTF (Ciliary neurotrophic factors); 31) CNTF derivatives, such as axokine (Regeneron); 32) monoamine reuptake inhibitors; 33) UCP-1 (uncoupling protein-1), 2, or 3 activators; 34) thyroid hormone .beta. agonists; 35) FAS (fatty acid synthase) inhibitors; 37) DGAT2 (diacylglycerol acyltransferase 2) inhibitors; 38) ACC2 (acetyl-CoA carboxylase-2) inhibitors; 39) glucocorticoid antagonists; 40) acyl-estrogens; 41) lipase inhibitors, such as orlistat (Xenical®); 42) fatty acid transporter inhibitors; 43) dicarboxylate transporter inhibitors; 44) glucose transporter inhibitors; 45) phosphate transporter inhibitors; 46) serotonin reuptake inhibitors; 47) Metformin (Glucophage®); 48) Topiramate (Topimax®); 49) opiate antagonists such as naltrexone, 50) the non-selective transport inhibitor bupropion, and/or 51) MAO inhibitors.

The compounds of the present invention are expected to be CB1 receptor blockers and are expected to be useful for treating diseases mediated by the CB₁ receptor. The compounds of the present are expected to possess an affinity in vitro for the central and/or peripheral cannabinoid receptors under the experimental conditions described by Devane et al., Molecular Pharmacology, 1988, 34, 605-613. The compounds according to the invention are also expected to possess an affinity for the cannabinoid receptors present on preparations of electrically stimulated isolated organs. These tests can be performed on guinea-pig ileum and on mouse vas deferens according to Roselt et al., Acta Physiologica Scandinavia 1975, 94, 142-144, and according to Nicolau et al., Arch. Int. Pharmacodyn, 1978, 236, 131-136.

CB1 receptor affinities can be determined using membrane preparations of Chinese hamster ovary (CHO) cells in which the human cannabinoid CB1 receptor is stably transfected (Biochem J. 1991, 279, 129-134) in conjunction with [3H]CP-55,940 as radioligand. After incubation of a freshly prepared cell membrane preparation with the [3H]-radioligand, with or without addition of test compound, separation of bound and free ligand is performed by filtration over glass fiber filters. Radioactivity on the filter is measured by liquid scintillation counting. The IC₅₀ values can be determined from at least three independent measurements.

Gelatin capsules can be obtained by mixing the active ingredient with a diluent and incorporating the resulting mixture into soft or hard gelatin capsules. A syrup or elixir can contain the active ingredient in conjunction with a sweetener, which is typically calorie-free, an antiseptic (e.g., methylparaben and/or propylparaben), a flavoring, and an appropriate color. Water-dispersible powders or granules can contain the active ingredient mixed with dispersants or wetting agents or with suspending agents such as polyvinylpyrrolidone, as well as with sweeteners or taste correctors. Rectal administration can be effected using suppositories, which are prepared with binders melting at the rectal temperature (e.g., cocoa butter and/or polyethylene glycols). Parenteral administration can be effected using aqueous suspensions, isotonic saline solutions, or injectable sterile solutions, which contain pharmacologically compatible dispersants and/or wetting agents (e.g., propylene glycol and/or polyethylene glycol). The active ingredient can also be formulated as microcapsules or microspheres, optionally with one or more carriers or additives. The active ingredient can also be presented in the form of a complex with a cyclodextrin, for example α-, β-, or γ-cyclodextrin, 2-hydroxypropyl-β-cyclodextrin, and/or methyl-β-cyclodextrin.

The dose of the compound of the present invention administered daily will vary on an individual basis and to some extent may be determined by the severity of the disease being treated (e.g., obesity, diabetes, liver diseases, cardiometabolic disorders, and cancers). The dose of the compound of the present invention will also vary depending on the compound administered. Examples of dosages of compounds of the present invention include from about 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 76, 80, 85, 90, 95, to 100 mg/kg of mammal body weight. The compound can be administered in a single dose or in a number of smaller doses over a period of time. The length of time during which the compound is administered varies on an individual basis, and can continue until the desired results are achieved (i.e., reduction of body fat, or prevention of a gain in body fat). Therapy could, therefore, last from 1 day to weeks, months, or even years depending upon the subject being treated, the desired results, and how quickly the subject responds to treatment in accordance with the present invention.

Synthesis

The compounds of the present invention can be prepared in a number of ways known to one skilled in the art of organic synthesis (e.g., see U.S. Pat. No. 6,476,060 B2, Biorg Med Chem Lett, 2005, 15, 4793 and U.S. Pat. No. 6,974,810). The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or by variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention. It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene and Wuts (Protective Groups In Organic Synthesis, Wiley and Sons, 1991). All references cited herein are hereby incorporated in their entirety herein by reference.

Scheme 1 shows how to convert 2′-, 3′-, or 4′-(carbo-t-butoxymethoxy)-2-phenylacetophenones, prepared from commercially available 2′-, 3′-, or 4′-methoxy-2-phenylacetophenones via O-demethylation using HBr/HOAc or BBr₃/CH₂Cl₂ and alkylation of the resultant phenol with t-butyl bromoacetate in the presence of base, in 37% aqueous formaldehyde containing piperidine under reflux to the corresponding acrylophenones (step a). Treatment of the acrylophenones with hydrazine hydrate in ethanol can produce the 3,4-diarylpyrazolines (step b). The diarylpyrazolines can be further treated with chlorosulfonylisocynanate in a solvent such as methylene chloride at about 0° C. to ambient temperature followed by an amine such as diethylamine to yield the diethylaminosulfonamide (step c). Conversion of these carbonyl compounds to the imidoyl chlorides could be carried out using phosphorus pentachloride in chlorobenzene at elevated temperatures (step d). Further exposure of these imidoyl chlorides to methylamine in methylene chloride at room temperature should afford the pyrazoline-1-carboxamidines (step e). Hydrolysis of the ester using TFA/CH₂Cl₂ should produce the carboxylic acid (step f).

Scheme 2 describes how 2-(2′-, 3′- or 4′-carbo-t-butoxymethoxyphenyl)acetophenones (prepared similarly to scheme 1) should provide the corresponding acrylophenones by treatment with formalin as previously described (step a). Treatment of the acrylophenones with hydrazine hydrate in ethanol can produce the 3,4-diarylpyrazolines (step b). The diarylpyrazolines can be further treated with morpholinosulfonyldithioimidocarbonic acid methyl ester (prepared from the morpholino-N-sulfonamide and carbon disulfide/methyl iodide (as described in Biorg Med Chem Lett 2005, 15, 4794; J. Med. Chem., 47, 627 (2004); Chem. Ber. 1966, 99, 2885) in a solvent like pyridine at elevated temperature to yield pyrazole-1-carboximidothioic acid methyl esters (step c). Further exposure of these iminothioethers to an aqueous solution of methylamine in methanol at room temperature should afford the pyrazoline-1-carboxamidines (step d). Hydrolysis of the ester using TFA/CH₂Cl₂ should produce the carboxylic acid (step e).

Scheme 3 shows the conversion of 4′-chloro-2-phenylacetophenone in 37% aqueous formalin and MeOH containing piperidine and acetic acid at reflux that should occur affording the acrylophenone (J. Agric. Food Chem. 1979, 27(2), 406)(step a). Treatment of the acrylophenone with hydrazine hydrate in ethanol can produce the 3,4-diarylpyrazolines (step b). The diarylpyrazoline can be further treated with chlorosulfonylisocynanate followed by diethyl amine to give the sulfonamide and chlorinated with phosphorus pentachloride, as previously described, to yield the imidoyl chloride (step c). Further exposure of these imidoyl chlorides to beta-alanine ethyl ester in ethanol or methylene chloride should yield the pyrazoline-esters (step d). Hydrolysis of the ester using lithium hydroxide in aqueous THF solution should produce the carboxylic acid (step e). Treatment of the ester with anhydrous ammonia in methanol at about 0° C. to room temperature can afford the carboxamido compound (step f). Alternatively, the iminothioethers can be coupled with di-amino acid esters to give adducts (step g) that can be hydrolyzed to carboxylic acids (step h). These acids may be converted to the carboxamides using oxalyl chloride in dichloroethane followed by anhydrous ammonia, or Boc₂O in pyridine/THF followed by anhydrous ammonia (step i).

Scheme 4 illustrates how oxidation of 4′-chloro-2-phenylacrylophenone in methylene chloride with m-chloroperbenzoic acid should provide the epoxide (step a), which upon treatment with hydrazine hydrate in ethanol solution at about 35-40° C. can give the 3,4-diarylpyrazoline alcohol (step b). The pyrazoline can be protected using di-t-butyl-dicarbonate (t-Boc anhydride) in the presence of a base to give the N-t-BOC-pyrazoline (step c). The carbamate alcohol can then be deprotonated with sodium hydride in a solvent like DMF, or lithium hexamethylsilazide in THF, followed by alkylation with ethyl 4-bromocrotonate to yield the ester (step d). Removal of the t-BOC group can be achieved via treatment with TFA (step e). The pyrazoline can then be reacted with dialkylaminosulfonyldithioimidocarbonic acid methyl esters in a solvent like acetonitrile in the presence of triethylamine at reflux to yield the pyrazole-1-carboximidothioic acid methyl ether (step f). Further exposure of these iminothioethers to a solution of methylamine at 0 degrees to room temperature can afford the pyrazoline-1-carboxamidines (step g), and hydrolysis of the ester using LiOH in aqueous THF solution can produce the carboxylic acid (step h). The carbxoamides can be prepared by treatment of the acid with isobutylchloroformate (IBCF) in the presence of N-methylmorpholine (NMM) in dichloromethane and anhydrous ammonia (step i).

Scheme 5 shows how treatment of a solution of the 3,4-diarylpyrazoline and chlorosulfonylisocyanate in dichoromethane at 0° C. to ambient temperature can form the chlorosulfonamide adduct (step a). Treatment of this sulfonyl chloride with an amino acid ester such as ethyl sarcosine in dichloromethane in the presence of triethylamine can give the sulfonamide ester adduct (step b). Conversion of this intermediate to the imidoyl chloride can be accomplished using phosphorus pentachloride in chlorobenzene at elevated temperature (step c), followed by treatment with methyl amine in MeOH at about 0° C. to room temperature can afford the N-methylamine adduct (step d). The carboxamide may be prepared by further conversion of the ester to the acid, and subsequent treatment with IBCF, NMM and ammonia as previously described (step e).

Scheme 6 depicts how condensation of a solution of 4′-nitro-2-phenylacetophenone in 37% aqueous formalin and MeOH containing piperidine and acetic acid should afford after heating at reflux, the corresponding acrylophenone (step a). Treatment of the acrylophenone with hydrazine hydrate in ethanol can produce the 3,4-diarylpyrazoline (step b). The pyrazoline can then be reacted with chlorosulfonylisocyanate in a solvent like dichoromethane at 0° C. to ambient temperature to yield the corresponding sulfonyl chloride (step c). Condensation of this intermediate with (methoxyethyl)ethylamine will afford the sulfonamide adduct (step d). Treatment of this intermediate with phosphorus pentachloride in chlorobenzene at elevated temperature should produce the imidoyl chloride (step e), and subsequent treatment with methyl amine in methanol can provide the methyl amino adduct (step f). The nitro group can be reduced using sodium dithionite in aqueous basic solution or with Fe in hydrochloric acid solution, to produce the aniline compound (step g). Acylation of the aniline with ethyl malonyl chloride in the presence of base should produce the amide (step h). Treatment of the amidoester with anhydrous ammonia in a solvent such as methanol or at zero degrees to room temperature should afford the pyrazole-1-carboxamidines with the terminal carboxamido group (step i).

Scheme 7 illustrates how treatment of 4′-cyano-2-phenylacrylophenone with hydrazine hydrate in ethanol will produce the 3,4-diarylpyrazoline (step a). The pyrazoline can then be reacted with tri-n-butyltin azide, conveniently prepared in situ by the reaction of one equivalent of sodium azide and one equivalent of tri-n-butyltin chloride (J. Med. Chem. 1991, 56, 2395), in reluxing toluene or xylene to afford the tri-n-butyltin-tetrazole adduct (step b). The tri-n-butyltin-adduct can be converted to the trityl-tetrazole adduct by treatment with one equivalent of aqueous sodium hydroxide solution and one equivalent of trityl chloride at about ambient temperature or above (step c). Reaction of this adduct with chlorosulfonylisocyanate in a solvent like dichoromethane at 0° C. to ambient temperature should yield sulfonyl chloride (step d). Condensation of this intermediate with diethylamine will afford the sulfonamide adduct (step e). Treatment of this sulfonamide with phosphorus pentachloride in chlorobenzene at elevated temperature should produce the imidoyl chloride (step f). Subsequent treatment with methyl amine in methanol can provide the methyl amino adduct, and removal of the trityl group with aqueous TFA in THF at room temperature should yield the unprotected tetrazole (step g).

One stereoisomer of a compound of the present invention may be a more potent cannabinoid receptor antagonist than its counterpart(s). Thus, stereoisomers are included in the present invention. When required, separation of the racemic material can be achieved by HPLC using a chiral column or by a resolution using a resolving agent such as described in Wilen, S. H. Tables of Resolving Agents and Optical Resolutions 1972, 308 or using enantiomerically pure acids and bases.

Tables 1a-2b show a variety of examples of compounds of the present invention that are expected to be synthesized using the routes described above.

The preparation of the diphenyl pyrazolines with optional substituents on the 3-phenyl group can be prepared according to the procedures previously described [see Biorg Med Chem Lett, 2005, 15, 4793; U.S. Pat. No. 6,974,810; J. Med. Chem., 2004, 47, 627; and, J. Agric. Food Chem., 1979, 27, 406]. The pyrazolines can be condensed with chlorosulfonylisocyanate and dialkyl amines as previously described. Chlorination of the product sulfonamides with phosphorus pentachloride in heated cholorbenzene can produce the imidoylchlorides which were readily converted to the various amino ester adducts as previously described Biorg Med Chem Lett, 2005, 15, 4793; [J. Med. Chem., 2004, 47, 627]. Conversion of these esters to acids, carboxamides, substituted carboxamides, or di-amino acid variants can be carried via conventional methodology.
